Discussed in http://lists.debian.org/debian-devel/2007/05/msg01173.html
With glibc-2.5 and gcc-4.1.2 (and gcc-4.2), the 'long double'
data type did change from a 64bit representation to a 128bit
representation on alpha, powerpc, sparc, s390. To allow
partial upgrades of packages, we will need to rename all
packages holding libraries with the long double data type in
their API. Both libc and libstdc++ do not need to be renamed,
because they support both representations. We rename the library
packages on all architectures to avoid name mismatches between
architectures (you can avoid the renaming by supporting both
datatype representations in the library as done in glibc and
libstdc++, but unless a library is prepared for that, it does not
seem to be worth the effort).
It is suggested to rename a package libfoo1 to libfoo1ldbl;
please wait with the renaming if the package depends on
another library package which needs renaming.
This package has been indentified as one with header files in
/usr/include matching 'long *double'. Please close this bug report
if it is a false positive, or rename the package accordingly.
